  • 1.  EVPN/MPLS MX Duplicate packet

    Hi !

    I'm facing an issue regarding EVPN configuration.

    Everything seems work fine but I can explain there are duplicate packets when I ping internet from PC or from internet to PC (see the attached file).

    Using EVE-NG as lab, I do not have this issue. I see the duplicate packets only in production.
    The goal of the implementation of EVPN/MPLS is to replace VRRP protocol, offer redundancy in case of gateway failure and provide a distributed gateway IP.
    That's why I have a layer 2 between the EX switches. In this use case, vlan 666 is configured on MX and EX. PC is also in this vlan with a /30 prefix.

    I tried with the same ESI and different ESi between PE but same result (all-active is used).

    Do you know what can explain this duplicate packets ?
    "show evpn instance extensive" shows that there is one designated forwarder and one backup forwarder.
    The routing table of instance.evpn.0 and bgp.evpn.0 is okay

    Thanks for your help !
